Gluing instructions
Safety notes
!
The included UHU-Holzleim is suitable for all of the required gluing processes. Carbon fiber and steel must be sanded before being glued and an hardening period of many hours is required.
General These safety instructions are intended not only to protect the product, but also for your own and other people’s safety. Therefore please read this section very carefully before using the product! Do not carelessly leave the packaging material lying around, since it might become a dangerous toy for children. Persons, including children, with reduced physical, sensory or mental capabilities, or lack of experience or knowledge, or not capable to use safely the Kleine UHU must not use the model without supervision or instruction by a responsible person. Operation and use of radio-controlled models needs to be learned! If you have never operated a model of this type before, start carefully and make yourself familiar with the model's reactions to the remote control commands. Proceed responsibly. Before you start using the remote control model, you have to check the further relevant laws and regulations. The user must be sure, before each use of RC model, about the functional safety and the proper condition of the RC model. The insurance is mandatory for all kinds of RC model operation. If the model is equipped with RC system (RC version), pay attention to the instruction included with the transmitter.

Procedure depending on the version Depending on whether you want to build the free-flight version or the RC version, the approach is different. If the model is assembled as free-flight version, it cannot be converted to RC version. Therefore pay attention to the related assembly steps sequence. (see diagram) Note To build the RC version you need the RC conversion kit No. 4616.90 (not included in the kit). Free-flight model

Assembly step 31 only for free-flight version Note The curve control function in the free-flight version: Starting point is a trimmed model that flies straight on. The trim rudder (28) is has that scope. After the towing start the curve control is released through an eyelet on the towing start ring (see separate towing start manual) and the model will start to circle because the right trim rudder is pushed under by the trim spring (30) of about 5°. Shorten the wire (27) from accessory No. 242. The manual of the "towing starter" are available in the web page of the product.

The painting It is not indispensable to paint the model, we however recommend it. Before and after the painting sand the surface with sanding paper No. 700.1. To protect the model against humidity, paint it once or twice with GLATTFIX pore filler. The decals Cut out the single writings and apply them to the desired parts of the model, as reference you can use the illustrations on the box. Blacken the canopy with a black pencil.

Procedure depending on the version Depending on whether you want to build the free-flight version or the RC version, the approach is different. If the model is assembled as free-flight version, it cannot be converted to RC version. Therefore pay attention to the related assembly steps sequence. (see diagram) Note To build the RC version you need the RC conversion kit No. 4616.90 (not included in the kit). Free-flight model

Assembly step 31 only for free-flight version Note The curve control function in the free-flight version: Starting point is a trimmed model that flies straight on. The trim rudder (28) is has that scope. After the towing start the curve control is released through an eyelet on the towing start ring (see separate towing start manual) and the model will start to circle because the right trim rudder is pushed under by the trim spring (30) of about 5°. Shorten the wire (27) from accessory No. 242. The manual of the "towing starter" are available in the web page of the product.

The painting It is not indispensable to paint the model, we however recommend it. Before and after the painting sand the surface with sanding paper No. 700.1. To protect the model against humidity, paint it once or twice with GLATTFIX pore filler. The decals Cut out the single writings and apply them to the desired parts of the model, as reference you can use the illustrations on the box. Blacken the canopy with a black pencil.
